How Duke vs Darian Mensah legal case could be precedent-setting in NIL space
The Duke vs Darian Mensah legal battle further intensified Wednesday.
The university filed suit seeking to prevent the quarterback, who led the Blue Devils to the 2025 ACC championship, from leaving to play football at another school. Mensah, who led the ACC in passing this past season, signed a two-year contract worth a reported $8 million with the school and Duke claims he’s attempting to breach the contract after one year.
In a statement issued Wednesday by a school spokesperson, the university said: “Mr. Mensah has entered an existing contract with Duke which the university intends to honor, and we expect he will do so the same. The university is committed to supporting all our student-athletes, while expecting each of them to abide by their contractual obligations.”
Duke said a temporary restraining order was sought Tuesday in Durham County Superior Court that “ensures he does not violate his contract.” The TRO was granted Wednesday and the next court hearing set for Feb. 2. Duke can enter Mensah into the portal, as he requested last Friday. But he’s not allowed to enroll and sign a deal with another school.
The lawsuit noted that the legal action comes in the “increasingly complex world of college athletics” while also noting it is a “simple case that involves the integrity of contracts.”
The fight over the value of a college athlete’s name, image and likeness has become increasingly complex and anything but simple. Mensah’s contract with Duke gave the school exclusive rights over his NIL rights during the course of the contract.
Given the winning of an ACC championship, Duke’s first in football since 1989, Mensah’s likeness would figure to be well-used in school promotions leading up to the 2026 season.
Mensah, who played at Tulane in 2024 before transferring to Duke last year, first said in December he would not enter the NFL Draft but would remain at Duke for a second season. But on Jan, 16, with the NCAA transfer portal about to close, he informed Duke coach Manny Diaz and athletic officials he planned to enter the portal.
While Mensah has not named an intended destination, it is widely believed he is being sought by the Miami Hurricanes to replace Canes quarterback Carson Beck.
Setting a precedent?
The messy legal situation with Mensah could be precedent-setting in the college sports setting, with so many college athletes looking to monetize themselves while playing, Triangle-based attorney David McKenzie said Wednesday.
“I think it could be and I think it should be,” he said. “I think Mensah is one of the higher-dollar players who has tried to breach an NIL deal. I think what makes this one really unique is its length. Usually NIL deals are year to year.
“In this case, Duke realized it was taking a risk by putting $8 million in just one player. In order to protect itself, as any prudent school would, it required several levers of breach should Mensah try to leave, and that’s exactly what happened.”
McKenzie, a Duke alumnus who specializes in intellectual property and Constitutional law, said there was a chance Mensah could decide to remain at Duke, play the 2026 season and fulfill his contract.
“Absolutely,” he said. “Whether or not Duke will allow that is another question, because by entering the portal Mensah has triggered a breach and Duke no longer has to honor a contract that’s in a breach.
“There’s a deeper question: What would the locker room look like should Mensah come back? What would Diaz want? I’m sure everybody feels burned at Duke, and for good reason, and I don’t think they would have quickly turned around and filed a lawsuit less than 72 hours after Mensah declared the portal if that wasn’t the case.”
Can Duke win suit vs. Mensah?
McKenzie also sees Duke coming out the winner once the suit goes to arbitration and that it could be resolved by mid-February.
“I have no problem with Duke creating a contract that really does put the screws to a player,” he said. “This is big-game hunting, When you come to a school like Duke and you take $4 million, and then halfway through (the contract) say I’m not going to perform, getting more money and leaving high and dry, Duke should be able to have ready recourse to get that money back and be made whole in full under that deal.”
Meaning?
“To get the $4 million back,” McKenzie said. “And my reading of the contract identified that as the damages. Usually, in a contract situation, if there’s a performance contract situation you look at what the replacement cost is. So, Mensah decides to leave for wherever, Duke then is stuck looking for a replacement quarterback and finds one for $2.5 million. In that scenario, Duke’s damages would be $1.5 million under a strict performance contract,
“What makes this different is that this was Mensah pledging his intellectual property as a license for Duke to exploit freely for a period of two years. … I think at the baseline, you are looking at damages of $4 million to Duke, and that doesn’t include what Duke is able to monetize from Mensah’s NIL for the next year. Those belong to Duke, so if Mensah goes to Miami and strikes a deal for $10 million for his NIL with Adidas, I’m sorry, bad news, that money goes back to Duke under the licensing deal.
“That last thing Duke needs across all sports including basketball is for athletes to think that the contracts they sign with Duke do not matter. Duke has way too much money at stake in its athletes and they are generous in what they give these athletes. I would think Duke would want to make it clear if you come to Duke University, we’re going to treat you fair and we expect you to live up to your contract.”
